A buried provision in HB381 creates a new state income tax on oil and gas pass-through entities—and the clock starts in 2028.
Most Alaska construction and trades business owners don't realize that HB381, which dealt primarily with oil and gas property tax and municipal revenue, contains a provision that could directly affect their bottom line if they work in oil and gas production, transportation, or supply.
Under Section 24 of HB381 (codified as AS 43.20.019(a), page 27), Alaska created a new graduated state income tax on certain oil and gas businesses. If your business is structured as a sole proprietorship, partnership, LLC, or S-corporation and you produce, transport, or supply oil or gas in Alaska, you are now classified as a "qualified entity" under the law.
Starting January 1, 2029, these qualified entities will owe a new state income tax of up to 9.4% on Alaska-sourced income. Previously, pass-through entities like LLCs and S-corps did not pay state income tax at the business level—income passed through to owners, who reported it individually. That structure is changing for oil and gas businesses.
Even though the tax doesn't apply until 2029, there is an immediate deadline you cannot miss: March 16, 2028.
By that date, any qualified entity must file a one-time informational return with the state. This return is required before the tax itself takes effect. Missing this deadline could create compliance problems and potential penalties. This is not optional, and it is not a tax payment—it is a filing requirement that establishes your status with the state.
If you operate in oil and gas supply, logistics, drilling support, equipment rental, or related trades, you should assume this applies to you unless your business structure clearly falls outside the definition.
Start by confirming whether your business qualifies as a "qualified entity" under the law. Review your business structure and the nature of your Alaska-sourced income. If you have any doubt, consult with a tax professional or accountant familiar with Alaska oil and gas operations.
Mark March 16, 2028, on your calendar. Plan to work with your accountant or tax advisor to prepare and file the informational return well before the deadline. This is not something to leave until the last week of March.
If your business will be affected, begin modeling the impact of a 9.4% income tax on your Alaska operations. This may affect pricing, profitability, or business structure decisions you make over the next few years.
